[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The non-wireless transmission production material in-and-out storage system of the present invention is provided with a handheld offline terminal, including a reading module, a compiling module, a display module, and an input module. The reading module is used to respond to the operation of the operator to read the material information contained in the identification code on the large material. The input module is used to respond to the operation of the operator to obtain the in-and-out quantity of the large material and the storage location number of the large material.

It is difficult to use a wired barcode scanner to scan the code at a certain point. For materials with larger volume, it is also difficult to use a wired barcode scanner due to the wiring length limitation of the wired barcode scanner. For these large materials, the operator can carry a handheld offline terminal to the material to be stored, scan or take a photo of the identification code on the material, read the information contained in the identification code, and generate the corresponding ferry QR code, and then carry the handheld offline terminal to the wired barcode scanner, and read the material information in the ferry QR code through the wired barcode scanner, so that the warehouse management system can identify the stored materials through the ferry QR code, effectively improving the efficiency of the storage operation; at the same time, the handheld offline terminal does not rely on the wireless network, can operate in a non-wifi environment, and has high security. Therefore, this design is conducive to the rapid storage of large materials by setting up a handheld offline terminal, effectively improving the efficiency of the storage operation, and has high security.

[0017] 2. In the non-wireless transmission production material in-and-out system of the present invention, the manufacturing execution system is connected to the warehouse management system by signal, and the warehouse management system is connected to the andon controller by signal through WebApi. The manufacturing execution system can give a list of outbound materials according to the BOM composition of the assembly parts or components, and pass it to the warehouse management system in the intranet environment. The warehouse management system can retrieve the warehouse location of the materials to be shipped in the list of materials and the inventory information of the materials to be shipped, and perform the outbound operation task through the andon controller, electronic tag, wired barcode scanner, and handheld offline terminal, and complete the outbound after verifying the accuracy of the outbound materials, so as to realize the complete outbound of the production materials of the assembly parts or components, and realize the automated and digital outbound management of the production materials. Therefore, this design realizes the complete outbound of the production materials of the assembly parts or components, and realizes the automated and digital outbound management of the production materials.

[0018] 3. In the manufacturing execution system of the non-wireless transmission production material in-and-out storage system of the present invention, the andon controller is connected to multiple electronic tags using a non-polarity two-wire wiring method. Each electronic tag is set corresponding to at least one storage location. The electronic tag includes a display screen, a button light, and an input button. The display screen can be used to display the number of the corresponding storage location and the inventory of the corresponding storage location. The button light is used to light up to indicate the storage location during the in-and-out operation. The input button is used to input the corresponding inventory data. The electronic tag has an automatic retrieval function. The light device on the electronic tag can guide the operator to quickly find the corresponding storage location. At the same time, the operator can output / enter the material quantity of the electronic tag. The warehouse management system modifies the inventory data accordingly according to the number of materials input by the operator to enter / enter the storage, thereby realizing semi-automatic warehouse management.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figures 1 to 5 A non-wireless transmission production material warehousing and warehousing system, the production material warehousing and warehousing system includes multiple andon storage locations for storing small materials and special storage locations for storing large materials, as well as a manufacturing execution system 1, a warehouse management system 2, an andon controller 3, a wired barcode scanner 5, a handheld offline terminal 6, and multiple electronic tags 4. The manufacturing execution system 1 can output the bill of materials of assemblies or components. The manufacturing execution system 1 is connected to the warehouse management system 2 through a wired network signal, and the warehouse management system 2 is connected to the andon controller 3 through a wired network. Specifically, the warehouse management system 2 and the andon controller 3 use WebApi (Web Application Programming Interface) as a bridge to achieve data exchange and function calls.

[0028] The warehouse management system 2 is a system in an intranet environment. The warehouse management system 2 is not connected to the Internet. At the same time, for discrete manufacturing enterprises that have higher requirements for information security and confidentiality in the production process, for information security considerations, the warehouse management system 2 and the andon controller 3 communicate using WebApi to avoid information security risks brought by wireless communication methods such as Bluetooth and WiFi.

[0029] The andon controller 3 is electrically connected to the wired barcode scanner 5 through a non-polarity two-wire interface device (AI-NET), and the wired barcode scanner 5 is used to read the material information contained in the identification code on the small material or the storage information contained in the ferry QR code. A non-polarity two-wire interface refers to an interface in an electrical or electronic device that uses two signal lines that do not distinguish between positive and negative poles for data transmission, power supply or other functions.

[0030] The ferry QR code is generated by the handheld offline terminal 6, which includes a reading module 61, a compiling module 62, a display module 63, and an input module 64. The reading module 61 is used to read the material information contained in the identification code on the large material, and the input module 64 is used to respond to the operation of the operator to obtain the in-and-out quantity of the large material and the warehouse location number of the large material. The compiling module 62 is used to compile the material information read by the reading module 61, the in-and-out quantity of the large material obtained by the input module 64, and the warehouse location number of the large material into a ferry QR code containing the in-and-out information, and the in-and-out information includes: the material information of the large material, the in-and-out quantity of the large material, and the warehouse location number of the large material. The ferry QR code can be read by the wired barcode scanner 5, and the display module 63 is used to display the ferry QR code.

[0031] Specifically, the handheld offline terminal 6 is a mobile phone equipped with a compiler program, wherein the compiling module 62 may be a WeChat applet, which encapsulates the compiling function on the WeChat platform, and the user can access and use the compiling function of the compiling module 62 through the WeChat client on the mobile phone. The compiling module 62 may also be a local application installed on the mobile phone, or an application program running in a browser such as a web application, which is not specifically limited here.

[0032] The identification code on the material is the identity of the material. The identification code contains the unique identification information of the material that can be recognized by the warehouse management system 2. Outside the non-wireless transmission production material in and out of the warehouse system, the identification code on the material is meaningless. The identification code on the material is a barcode. After the identification code is scanned, a string of codes with specific rules can be obtained. The code is read into the warehouse management system 2, and the information contained in the corresponding identification code can be matched in the warehouse management system 2, specifically including: the name of the material, specification model, project to which it belongs, and drawing number information, wherein the drawing number information is the number of the material on the drawing. The information contained in the identification code may also include other information such as batch number and production date, which is not specifically limited here. The information contained in the identification code is crucial for the tracking and management of materials. Setting an identification code on the material can realize the rapid identification and tracking of the material, improve the efficiency and accuracy of warehouse management, and realize automated warehouse management. The identification code on the material can also be a QR code.

[0033] The production material in-and-out storage system also includes a plurality of electronic tags 4, each of which is set in correspondence with an electronic tag 4, that is, each storage location in the warehouse has an electronic tag 4 corresponding thereto, and the electronic tag 4 is set at the corresponding storage location of the andon. Specifically, the electronic tag 4 can be installed on the shelf of the corresponding storage location of the andon, or at a position near the corresponding storage location where there is no line of sight obstruction. The electronic tag 4 is also installed at a position at the corresponding storage location that is easily observed by the operator according to specific needs, warehouse layout, and personnel operating habits, so as to ensure that the status of the button light 42 can be quickly noticed when needed, and the button light 42 can prompt the operator to quickly find the corresponding operation storage location.

[0034] The electronic tag 4 includes a display screen 41, a button light 42, and an input button 43. The display screen 41, the button light 42, and the input button 43 are all electrically connected to the andon controller 3 using a non-polarity two-wire wiring method (AI-NET). The button light 42 is used to highlight the storage location for inbound and outbound operations. The input button 43 is used to respond to the operator's operation to obtain the number of small materials in and out of the storage. The display screen 41 is used to display the number of the corresponding storage location and the number of materials in and out of the corresponding storage location. The non-polarity two-wire wiring method refers to the use of two wires for data transmission, power supply or other functions in electrical equipment or systems, and the two wires are not distinguished by positive and negative poles when connected, that is, there is no clear + and - polarity identification.

[0035] Specifically, the content displayed on the display screen 41 consists of two parts, one part is the number of the storage location corresponding to the electronic tag 4, and the other part is the number of materials taken out / put in this out / in operation input by the operator through the input button 43, such as Figure 5 As shown, Figure 5 The electronic tag 4 corresponding to the storage location No. 5 has a display screen 41 showing the storage location number as 5. This entry / exit operation requires taking out / putting in 10 pieces of materials, so the number of materials entered by the operator through the input button 43 is 10.

[0036] The button light 42 can be an LED key light. The button light 42 is an electrical component that combines lighting and switch functions. When the button light 42 is on, it means that the storage location corresponding to the button light 42 is performing an in / out storage operation. The operator can quickly find the operation storage location through the button light 42. The button light 42 can also indicate the storage or out operation through different lighting colors. For example, the button light 42 lights up in blue to represent the storage operation, and the button light 42 lights up in yellow to represent the out-of-stock operation, so as to prompt the operator. At the same time, when the in / out storage operation is completed, the operator presses the button light 42. At this time, the button light 42 sends a button signal to the andon controller 3 to prompt that the in / out storage operation is completed, and then the button light 42 goes out and the display screen 41 stops displaying.

[0037] The input button 43 is used to input the quantity of materials taken out / put in this out / in operation to the andon controller 3 according to the key operation of the operator. At the same time, the andon controller 3 controls the display screen 41 to display the quantity of materials taken out / put in this out / in operation according to the input of the input button 43. Figure 5 As shown, the input button 43 includes two buttons, namely, the input+ button and the input- button. By clicking or pressing the input+ button and the input- button, the quantity of materials taken out / put in this out / in storage operation displayed on the display screen 41 can be increased or decreased.

[0038] The warehouse is equipped with multiple andon storage locations and at least one special storage location. The andon storage location is used to store small materials, which are materials whose weight does not exceed the preset weight threshold and whose volume does not exceed the preset volume threshold. The special storage location is used to store large materials, which are materials whose weight exceeds the preset weight threshold and / or whose volume exceeds the preset volume threshold. When performing material warehousing operations, different warehousing methods and different storage locations can be selected according to the material form, weight, and distance from the warehouse.

[0039] In summary, the embodiment of the present invention provides a non-wireless transmission production material in-and-out system, which includes three parts: a manufacturing execution system 1, a warehouse management system 2, and an andon control system. Through the integration of the warehouse management system 2 with the manufacturing execution system 1 and the integration of the warehouse management system 2 with the andon controller system, the distribution of the complete set of assembly production material data and the interaction of warehouse production material inventory data are realized. Among them, the manufacturing execution system 1 mainly provides production material information to the andon controller 3 as the data source. The manufacturing execution system 1 is not directly connected to the andon controller 3. The warehouse management system 2 serves as a "bridge" between the manufacturing execution system 1 and the andon controller 3, and completes operations such as out-of-warehouse, in-warehouse and inventory query through a visual user interface. The warehouse management system 2 and the andon controller 3 communicate with each other through WebApi, and the warehouse management system issues instructions. The basic instructions include the light-on instruction (SendLighting), the light-off instruction (SendModuleOFF), the subtitle display instruction (SendLightModule), etc. The instructions are flexibly combined according to different scene applications to meet the needs of different operation tasks.

[0040] The warehouse management system 2 communicates with the Andon controller 3 in the form of WebApi, and the Andon controller 3 is provided with a WebApi heartbeat program. The Andon controller 3 sends a heartbeat message to the warehouse management system 2 every 100 milliseconds through the WebApi heartbeat program, and calls back the URL every 100 milliseconds through the heartbeat program to achieve a fast response between the Andon controller 3 and the warehouse management system 2. At the same time, the Andon controller 3 and the electronic tag 4 are connected to the power supply chip through a two-wire transmission signal to achieve fast communication.

[0041] A non-wireless transmission production material in-and-out storage method, the in-and-out storage method is based on the above-mentioned non-wireless transmission production material in-and-out storage system, and the in-and-out storage method includes an out-of-stock method and an in-stock method; The method for removing goods from storage comprises the following steps: The manufacturing execution system 1 generates a list of materials to be shipped out, and sends the list of materials to be shipped out to the warehouse management system 2; The warehouse management system 2 receives the list of materials to be shipped out, and retrieves the number of the storage location of each material in the list of materials to be shipped out in the database, determines whether each material is located in the andon storage location or the special storage location according to the number of the storage location of each material, executes andon shipment for the materials to be shipped out located in the andon storage location, and executes offline terminal shipment for the materials to be shipped out located in the special storage location; The execution of the andon warehouse release comprises the following steps: The warehouse management system 2 sends a button light lighting instruction and a display instruction to the andon controller 3 according to the number of the warehouse location where the materials to be shipped are located; The andon controller 3 controls the button light 42 of the corresponding numbered storage location to light up in the first color according to the button light lighting instruction, and the andon controller 3 controls the display screen 41 of the corresponding numbered storage location to start up according to the display instruction; wherein, the button light 42 of the corresponding numbered storage location is the button light on the electronic tag 4 corresponding to the storage location, the display screen 41 of the corresponding numbered storage location is the display screen on the electronic tag 4 corresponding to the storage location, and the input button 43 of the corresponding numbered storage location is the input button on the electronic tag 4 corresponding to the storage location.

[0042] After the button light 42 of the corresponding numbered storage location lights up, the operator quickly finds the corresponding numbered storage location according to the indication of the button light 42, and then the operator inputs the quantity of materials taken away through the input button 43 of the corresponding numbered storage location. The input button 43 of the corresponding numbered storage location responds to the operator's operation and sends the quantity information of the outbound materials to the andon controller 3. The andon controller 3 receives the quantity information of the outbound materials and controls the display screen 41 of the corresponding numbered storage location to display the quantity of the outbound materials according to the quantity information of the outbound materials. When the operator takes the materials to be shipped out from the corresponding numbered storage location, the operator presses the button light 42 on the corresponding numbered storage location. The button light 42 of the corresponding numbered storage location responds to the operator's operation and sends a button signal to the andon controller 3. The andon controller 3 receives the button signal and sends feedback information to the warehouse management system 2 according to the quantity information of the shipped materials. After receiving the feedback information, the warehouse management system 2 sends a button light off instruction to the andon controller 3, and updates the inventory information of the corresponding materials in the database according to the feedback information. The andon controller 3 controls the button light 42 of the storage location with the corresponding number to turn off and the display screen 41 to turn off according to the button light off instruction.

[0043] The execution of offline terminal outbound delivery includes the following steps: The operator scans the identification code on the material to be shipped out through the reading module 61 on the handheld offline terminal 6. The reading module 61 reads the material information contained in the identification code on the material to be shipped out in response to the operator's operation; The operator inputs the quantity of the materials to be shipped and the warehouse location number of the materials to be shipped through the input module 64 on the handheld offline terminal 6, and the input module 64 obtains the quantity of the materials to be shipped and the warehouse location number of the materials to be shipped in response to the input operation of the operator; The compiling module 62 compiles the material information read by the reading module 61 and the quantity and the storage location number of the materials to be shipped obtained by the input module 64 into a ferry QR code containing the shipping information. The shipping information includes the material information, quantity and storage location number of the materials to be shipped. The display module 63 displays the ferry QR code; After the operator takes the materials to be shipped out from the corresponding storage location, he uses the wired barcode scanner 5 to scan the ferry QR code displayed on the display module 63. The wired barcode scanner 5 reads the shipping information contained in the ferry QR code in response to the operator's operation, and sends the shipping information to the warehouse management system 2 through the andon controller 3; The warehouse management system 2 receives the outbound information and updates the inventory information of the corresponding materials in the database according to the outbound information.

[0044] The warehousing method comprises the following steps: If the material to be stored is a small piece, the material to be stored must be stored with an andon. If the material to be stored is a large piece, perform offline terminal storage for the material to be stored.

[0045] The execution of ANDON warehousing includes the following steps: The operator uses the wired barcode scanner 5 to scan the identification code on the material to be stored. In response to the operator's operation, the wired barcode scanner 5 reads the material information contained in the identification code on the material to be stored and sends the material information to the andon controller 3; The andon controller 3 receives the material information and sends it to the warehouse management system 2. The warehouse management system 2 allocates storage locations for the materials to be stored according to the material information, and sends button light lighting instructions and display instructions to the andon controller 3 according to the allocated storage locations; The andon controller 3 receives a button light lighting instruction and a display instruction, and controls the button light 42 of the assigned storage location to light up in a second color according to the button light lighting instruction, and controls the display screen 41 of the assigned storage location to start up according to the display instruction; wherein, the button light 42 of the assigned storage location is the button light on the electronic tag 4 corresponding to the assigned storage location, the display screen 41 of the assigned storage location is the display screen on the electronic tag 4 corresponding to the assigned storage location, and the input button 43 of the assigned storage location is the input button on the electronic tag 4 corresponding to the assigned storage location.

[0046] After the button light 42 of the assigned storage location lights up, the operator inputs the quantity of incoming materials through the corresponding input button 43. The input button 43 of the assigned storage location responds to the operator's operation and sends the quantity information of incoming materials to the andon controller 3. The andon controller 3 receives the quantity information of incoming materials and controls the display screen 41 of the assigned storage location to display the quantity of incoming materials according to the quantity information of incoming materials. After the operator puts the materials to be stored in the assigned storage location, he presses the button light 42. After the button light 42 of the assigned storage location sends a button signal to the andon controller 3 in response to the operator's operation, the andon controller 3 receives the button signal and sends feedback information to the warehouse management system 2 according to the quantity information of the stored materials. After receiving the feedback information, the warehouse management system 2 sends a button light off instruction to the andon controller 3, and updates the inventory information of the corresponding materials in the database according to the feedback information. The andon controller 3 controls the button light 42 of the allocated storage location to turn off and the display screen 41 to turn off according to the button light off instruction.

[0047] The execution of offline terminal storage includes the following steps: The operator uses the reading module 61 on the handheld offline terminal 6 to scan the identification code on the material to be stored. The reading module 61 reads the material information contained in the identification code on the material to be stored in response to the operator's operation; The operator inputs the quantity of the materials to be stored and the storage location number of the materials to be stored through the input module 64, and the input module 64 obtains the quantity of the materials to be stored and the storage location number of the materials to be stored in response to the input operation of the operator; The compiling module 62 compiles the material information read by the reading module 61 and the quantity and storage location number of the incoming materials obtained by the input module 64 into a ferry QR code containing outbound information, wherein the outbound information includes the material information, quantity and storage location number of the incoming materials; The display module 63 displays the ferry QR code; After the operator places the materials to be stored in the corresponding storage location according to the storage location number of the materials to be stored, the operator uses the wired barcode scanner 5 to scan the ferry QR code displayed on the display module 63. The wired barcode scanner 5 reads the outbound information contained in the ferry QR code in response to the operator's operation, and sends the outbound information to the warehouse management system 2 through the andon controller 3; The warehouse management system 2 receives the outbound information and updates the inventory information of the corresponding material in the database according to the outbound information. The inventory information of the material includes the material information, the storage location number of the material, and the inventory quantity of the material.

[0048] For the storage of large and small materials, small materials can be directly moved to the wired barcode scanner 5 for scanning, and then the wired barcode scanner 5 can be used to read the information contained in the identification code on the materials to be stored. For large materials, due to the weight and volume of large materials, it is difficult to move them to a fixed location and use a wired barcode scanner to scan them, and due to the limited length of the connection line, it is difficult for the wired barcode scanner to scan and read the identification code on large-volume materials. Therefore, for materials of large weight and volume, the operator can carry a handheld offline terminal to the materials to be stored, scan or take a photo of the identification code on the material to read the information contained in the identification code, and generate a corresponding ferry QR code based on the information contained in the identification code, and then carry the handheld offline terminal to the wired barcode scanner, and read the material information in the ferry QR code through the wired barcode scanner, so that the warehouse management system can identify the stored materials through the ferry QR code, effectively improving the efficiency of the storage operation.

[0049] When the number of large materials to be stored is greater than 1, the handheld offline terminal 6 is used to read the information contained in the identification code on a material by scanning or taking a photo, and after obtaining the storage information such as the storage quantity and storage location number of the large material through the input module 64, the storage information of the material is cached in the memory of the handheld offline terminal 6, and then the identification codes on other materials to be stored are photographed or scanned in the same way, and the storage information of the next material is cached in the memory of the handheld offline terminal 6 until the information of all materials to be stored is entered into the handheld offline terminal 6. Subsequently, the handheld offline terminal 6 merges the information of all the materials to be stored that have been entered and compiles the information of all the materials to be stored into a ferry QR code for display. The ferry QR code can contain the information of all the materials to be stored in the form of XML or other languages. By using the wired barcode scanner 5 connected to the warehouse management system 2 in the intranet environment, the above-mentioned storage ferry QR code can be scanned to read the storage information of multiple materials, and complete the long-distance material storage in a non-wireless network environment.
